Who knows the complete meaning of divination, yang divination, yin divination and holy divination during sacrifice?

If a person's relatives are gone, what do these three hexagrams mean? Generally speaking, it is good to have a holy divination, because one of the three divinations (including three divinations) is good when one asks. If it is exceeded, it is full yin divination or full yang divination, or both, which generally represents the concern of the deceased for that person. There must be a more detailed explanation, and I hope that netizens will deeply solve their doubts.
